In the early 1980s, Nicholas P. Franks and William R. Lieb demonstrated that the Meyer-Overton correlation can be reproduced using a soluble protein. They found that two classes of proteins are inactivated by clinical doses of anaesthetic in the total absence of lipids. These are luciferases, which are used by bioluminescent animals and bacteria to produce light, and cytochrome P450, … WebHere the authors show anesthetics directly target a subset of plasma membrane lipids to activate an ion channel in a two-step mechanism. Applying the mechanism, the authors …
